Oh, if I’m remembering correct I also ran a firmware upgrade of the USB3.0-controller after the step
“Installed (what i remember as the same as before) 184.108.40.206 driver”
downloaded from Asus webpage:
and under USB:
“USB 3.0 Boost Full Package Version V1.00.05”
In this executable they seem to have bundled a firmware upgrade for the controller among other things.
Note: For some reason I never got through the installation of the “Boost software” and the software got stuck, but got my firmware upgraded before that anyhow.
